s claims. (Cl. 114-208) lOur invention relates to new and usefulimprovements in collapsible boat anchors, particularly anchors for usewith the sports of boating and iishing wherein relatively small boatsareutilized, the principal object and essence of our invention being tovprovide a device of the character herewithin described which isfoldable for storage and yet which is highlyeffective when in use.

ln thesport of fishing` and boating, it is usual to use either a rock onthe end of a rope or a small solid anchor when it is desired to anchorthe boat in any particular location remote from the shore. The rock hasobvious disadvantages and the small solidanchor not only is a hazard ina small boat, but voften getsjammed in the rocky bottom of many of theinland lakes.

Our invention overcomes these disadvantages byproviding an anchor whichis collapsible when in the boat yet which opens out when ready for usereadily and easily. Furthermore, due to the novel construction of ouranchor, it is virtually impossible for same to become jammed on the lakebottom due to the fact that the snatch clip can readily be removed homthe shank thus enabling the pull to be directed to the base of theanchor rather than the upper end of the shank.

Another object of our invention is to provide a device of the characterherewithin described which is drawn up from the lake bottom in theretracted position therefore reducing considerably the tendency ofconventional anchors to engage Weeds, moss, etc.

Yet another object of our invention is to provide a device of thecharacter herewithin described in which the eective weight can readilyand easily be changed according to circumstances.

Still another object of our invention is to provide a device of thecharacter herewithin described which, when collapsed, is extremelycompact and easily stored.

With the foregoing objects in view, and such other objects andadvantages as will become apparent to those skilled in the art to whichthis invention relates as this specication proceeds, our inventionconsists essentially in the arrangement and construction of parts all ashere inafter more particularly described, reference being had to theaccompanying drawings in which:

Figure l is a. perspective View of our anchor in the extended position.

Figure 2 is a side elevation of our anchor in the raising position.

Figure 3 is an enlarged fragmentary section elevation of our anchor.

Figure 4 is an enlarged perspective View of the snatch clip and rope perse.

In the drawings like characters of reference indicate correspondingparts in the different gures.

Proceeding therefore to describe our invention in de tail, referenceshould be made to the accompanying drawings in which it will be seenthat we have provided an elongated shank 1 preferably of squarecross-sectional configuration. A base plate 2 is provided ofsubstantially standing lugs 7 between which are supported the inner ends8 of curved flukes 9. ln this connection, a pivot pin lll passes throughthe lugs and through a bearing 1.1 on the fluke end 8 so that the ukesare permitted to pivot within limits upon the base.plate. However, asthe lugs are fed inboard ofthe edges 6, the llukes cannot extend beyondthe position shown in Figure l.

A cylindrical weight 12 is apertured centrally to slide freely alongshank 1, said Weight being provided with a plurality of grooves 13 uponthe sides thereof. Pivot pins 14 span these grooves and act as supportfor one end 15 of links 16. The other or outer ends 17 of the links 16are pivotally engageable between lugs 18 formed upon the inner faces 19of the aforementioned ukes 9, pivot pins 20 connecting the links to theflukes. From the foregoing, it will be appreciated that when vthe weightis adjacent the base plate 2 as shown in Figure l, the links 16extendthe tlukes'totheir fullest extent, but when the weight is slidalongv towards the upper end 21 of the shank l, then the links i6 drawthe flukes upwardly so that they lie alongside, the shank l as clearlyshown in Figure 2. The Weight 12 is variable in effect by the pro visionof one or more segments 12' which may be secured to the upper end of theweight by set screws as shown in Figure 1.

We have provided means for extending or retracting the anchor asdesired, and in this connection a lifting ring 22 is secured to theunderside 23 of the base plate 2. The anchor rope 24 is secured to tln'sring by the lower end 25 of the rope and a snatch clip 26 is lsecured tothe rope a distance spaced from this lower end 2S. This snatch clip isspring-loaded and is preferably of square cross-sectional conigurationas shown in Figure 4 so that same will engage firmly around the shank land will only be displaced by a relatively sharp jerk. y

ln operation, the anchor is preferably stored within the boat in theposition shown in Figure 2. However, when it is desired to use theanchor, it is up-ended with respect to Figure2 so that the Weight 12descends by gravity towards the base plate 2 thus extending the llukes9. The rope is secured to the lifting ring 22 and the snatch clipengaged around the shank l so that the anchor takes up the positionshown in Figure l whereupon it may be lowered to the lake bed andengaged in the usual manner.

lt will be observed that the normal steady strain upon the anchor ropewill not disengage the clip and that the anchor will act as a normalanchor under these circumstances. However, when it is desired to raisethe anchor, a sharp jerk or snatch is given to the anchor rope thusdisengaging the clip 26 from the shank 1. This enables the strain to beplaced directly upon the lifting handle 2 which up-ends the anchor,disengages sarne from any obstruction, and permits sarne to be raisedreadily.

As soon as the anchor is up-ended, the weight l2 moves towards the end21 of the shank thus closing the ilukes to the position shown in Figure2 so that the anchor can readily be Withdrawn and lifted from the waterby means of the lifting ring 22. lt will also be observed that any mossor Weeds would automatically clear as the anchor is raised through thewater in this position.

lf it is desired merely to move the position of the anchor, then asteady pull on the rope 24 will disengage the anchor normally withoutdisengaging the snatch clip whereupon it can be raised clear of thebottom and be replaced when the boat has been re-positioned.

Since various modifications can be made in our inven- Y tion ashereinabove described, andmany apparently widely diierent embodiments ofsame n'iadevwithin the spirit and scope of the claims Without departingfrom such spirit and scope, Vit is intended that vall matter containedin the accompanying specication shall be interpreted as illustrativeVonlyand not in a limiting sense.

W'hat We claim as Vour invention is:

l. A collapsible boat anchor comprising in combination a shank, Va baseplate secured to one end of said shank, and a plurality of linkespivotally connected by'one end thereof to said base plate, a Weight onsaid Vshards sidable `therealong, and links pivotally connecting each ofsaid'ukes to said weight whereby when said Weight is adjacent said baseplate, Vsaid Ylinkes are extended and `when said Weight is towardstheopposite end of said shank, said dukes are retracted, against saidshank.

V2. The ydevice according Vto claim lV which` includes an anchor ropesecured lto said base plate and a snatch clip .secured to said rope anddetachablyxsecurable to saidshank.`

pluralityio .longitudinalY grooves .in .the Asides of said weight, saidlinks being pivoted within said grooves, the other ends of said linksbeing connected to said ukes intermediate the ends thereof. l i

5. The device according to claim l in which said weight is provided witha plurality of .segments detachably securable thereon for varying theeiect ofsaid weight.

6. The device YaccordingY Yto claiin 2` in 'which' said weight isprovidedrwith aiplurality ofsegments detachably securable thereon forV:varying theefect of said Weight. Y Y Y Y 7.
